Question 357: Centre of Mass and Rotational Motion

Question

A batsman hits a ball of mass 0.2 kg straight towards the bowler without changing its initial speed of $$6 \mathrm{~m} / \mathrm{s}$$. What is the impulse imparted to the ball?

Accepted Answer

The impulse is equals to change in linear momentum.
$$\begin{aligned}
	ext { Change in momentum } & =m(v-u) \
& =0.2(-6-6)=-2.4
\end{aligned}$$
The negative sign shows the direction of impulse is from batsman to bowler.
